The Prophet (may Allah's peace and blessings be upon him) used to admonish his Companions, advise them, and encourage them to aim at sublime matters, so that the worldly life would be in their hands, not in their hearts, and what they gained thereof would help them in acts of worship. This Hadīth contains guidance from the Prophet (may Allah's peace and blessings be upon him) to his Ummah that a person should not tire himself in seeking more than mere subsistence, for what is commendable in sustenance is the amount that enables a person to perform worship and for which he should work as much as needed. So, the Prophet (may Allah's peace and blessings be upon him) informed that success is attained and gained by a person who embraces Islam rightly, for he gets rid of Kufr (disbelief) and Shirk (polytheism), which is the sin that Allah does not forgive, and he is provided with mere subsistence, no more or less, and what makes him self-sufficient and saves him from necessities and wants. This means lawful sustenance, for no success comes with unlawful sustenance. And his words: "and Allah makes him content with what He has given him," i.e., Allah grants him contentment with the mere subsistence he has; so, he does not aspire to pursue more than that. The Hadīth shows that success and triumph are attained by embracing Islam for the sake of Allah and being pleased with what Allah gives him. It demonstrates the merit of contentment, and that it is one of the means of success..
